Allowing you to use CoffeeScript anywhere JavaScript is used.
CoffeeScript has a simple syntax, inspired by Ruby and Python, that is easy to read and write.
CoffeeScript allows you to check for existence and doesnt have a `var` keyword.
CoffeeScript can use any JavaScript library or package.
Handle multiple return values from a function or multiple properties from an object.
Use which ever paradigm you want: functional, object-oriented or imperative programming.
Every language has its own way of doing things. CoffeeScript is no different. Our mentors will help you learn to think like a CoffeeScript developer and how to write idiomatic code in CoffeeScript. Once you've solved an exercise, submit it to our volunteer team, and they'll give you hints, ideas, and feedback on how to make it feel more like what you'd normally see in CoffeeScript - they'll help you discover the things you don't know that you don't know.
